"We’re excited to announced a new membership tier. Now, for just $25, you can become an Annual LPU member and receive an LPU11 membership laminate and lanyard which will give you early entry to Linkin Park shows. You’ll also get all of the other LPU benefits for a whole year including opportunities for meet & greets, pre-sale tickets, LPU-TV episodes, exclusive music, access to the online community and more. These members will also be able to purchase passes to International LPU Summit events for an additional fee. LPU11 PLUS Membership tier is still available for $60 and includes the full membership package and FREE pass to Summit events. The $10 monthly pass is no longer available for purchase. If you haven't renewed from LPUX, you can check out this new membership option at LPUnderground.com.
For those of you who purchased the $60 LPU11 Annual Membership up until this point, we'd like to thank you for your dedication by guaranteeing that you will be selected for ONE meet & greet during the upcoming Linkin Park tour cycle.
